What Our Heating Service Includes
Heating systems work hard through long winter seasons, which is why thorough care makes such a difference. During a service visit, we perform a detailed inspection and tune-up to ensure your system is safe, efficient, and ready for cold weather.
Our service may include:
- Inspecting burners, heat exchangers, and ignition components
- Testing safety controls and electrical systems
- Checking blower motors and airflow
- Cleaning or replacing filters
- Verifying gas pressure and combustion efficiency (for gas furnaces)
- Confirming heat pump switching and defrost operation
- Testing thermostat accuracy
- Identifying early wear, efficiency loss, or safety concerns
After the visit, we review everything with you so you know the exact condition of your system — and what you can expect moving forward.
Heating Repairs You Can Count On
If your heat stops working, starts making unusual sounds, or isn’t keeping your home as warm as it should, our team is ready to help. We diagnose problems quickly and accurately so you don’t have to spend days in a cold house trying to guess what’s wrong.
Common issues we repair include:
No heat or inconsistent heating
Short cycling

We focus on fixing the root cause — not just patching symptoms — so your system stays reliable long after we leave.

EXCELLENT Based on 146 reviews Posted on Sarah SteinTrustindex verifies that the original source of the review is Google. We just had Dave’s come out to our house today. We thought we might have a serious issue with our heating and air system. The two technicians cleaned and serviced the unit and let us know that our unit was fine. We went from thinking we had an expensive problem to only having to pay a very reasonable service fee. They were professional and wonderful to work with. We will be using the company in the future and will recommend them to others.Posted on Eric MoyTrustindex verifies that the original source of the review is Google. I scheduled online for an AC diagnostic which was seamless. Adam came out in that time frame and gave me the run down of the issues. He was very knowledgeable and I would've went with him to fix the compressor issues. Unfortunately, whoever this companies receptionist is sounds like she hates her life over the phone. It took them a week to get back to me with a quote. She calls me, asks if I want to get it fixed and immediately asks for my credit card info. I don't have an estimate of what's being repairs or materials they need. I tell her please send it over and I'll pay the down payment through the portal since I was driving to work. A day goes by and crickets, I get another call asking about payment. She says she sent the email but the only thing I received was a schedule confirmation. Finally it arrives and everything is still lumped into one price. It wasn't that big of a deal, but I decided to get a second quote and this other place turned an itemize quote around in an hour, came out the next day, didn't ask for a deposit, and got the job done. If you all get that much business, the sentiment is your customers are just a number, and you can't be bothered to give the bare minimum customer experience then so be it.Posted on Jan and Joe AdamsTrustindex verifies that the original source of the review is Google. Great job. Dave’s assisted with design as this was a replacement of a chiller system. Very pleased. Adam and team doing the installation we awesome.Posted on David LoughranTrustindex verifies that the original source of the review is Google. Good experience from start to finish. Notification of appointments and arrivals. All members of the team were professional and polite. This was for a whole house steam humidifier.Posted on Cheryl WackerTrustindex verifies that the original source of the review is Google. I needed a new AC system due to RELAC out of business. Todd was my first contact. He explained my options, answered all my questions...even after he left and I continued to contact him. He was very patient with all my concerns. On the install day, Adam and his team arrived on time, and communicated with me during the entire process. They explained thoroughly what they were doing and why. They did not leave until all had been checked out, and they cleaned up thoroughly. I will recommend them to anyone needing a new AC system.Posted on nora bTrustindex verifies that the original source of the review is Google. I’ve been a Dave’s customer for over 20 years.
